Just updated! Trilobites are cool looking also are the right size and anyone can look for them. The ones you find you get to keep! How cool is that? My son is holding this gem. On his first hunt we found this one. This one is called a Flexicalymene Meeki.

Picture of the trilobite before I started. Can you see where it is?

You can see about half of it. The trilobite is on its side.

A Flexicalymene Meeki. It is the common trilobite found around here.

Fetching RSS feed... please stand byTrilobites ("three-lobes") are extinct arthropods that form the class Trilobita. They appeared in the Early Cambrian period and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Late Devonian extinction, all trilobite orders, with the sole exception of Proetida, died out. The last of the trilobites disappeared in the mass extinction at the end of the Permian about 250 million years ago (m.y.a.).
Trilobites are very well-known, and possibly the second-most famous fossil group, after the dinosaurs. When trilobites appear in the fossil record of the Lower Cambrian they are already highly diverse and geographically dispersed. Because of their diversity and an easily fossilized exoskeleton, they left an extensive fossil record with some 17,000 known species spanning Paleozoic time. Trilobites have been important in biostratigraphy, paleontology, and plate tectonics research. For example, trilobites have been important in estimating the rate of speciation during the period known as the Cambrian Explosion because they are the most diverse group of metazoans known from the fossil record of the early Cambrian, and are readily distinguishable because of complex and well preserved morphologies. The trilobites are often placed within the arthropod subphylum Schizoramia within the superclass Arachnomorpha (equivalent to the Arachnata), although several alternative taxonomies are found in the literature.
Different trilobites made their living in different ways. Some led a benthic life as predators, scavengers or filter feeders. Some swam (a pelagic lifestyle) and fed on plankton. Most life styles expected of modern marine arthropods are seen, except for parasitism.
Some trilobites (particularly the family Olenida) are even thought to have evolved a symbiotic relationship with sulfur-eating bacteria from which they derived food.

Great lens, 5 stars. So that's where you find trilobites. Wonder if it's possible to find trilobites in Manhattan? [Mine came from a store. Oh well.] Posted March 15, 2008 |
Go to webshots.com and search for trilobites.
